Carl:
I use VirtualBox on Debian 12, and I run virtual Windows 11 and Linux machines with no issue. I also tried GNOME
boxes and had no direct problems, but I went back to using VirtualBox because it was compatible with my cloud storage setup - I can save a VirtualBox virtual machine file in the cloud server and access it from my desktop and laptop without issue, whereas GNOME
boxes wouldn’t work if I did that - there were always boot errors. But GNOME boxes otherwise seemed to work great.
